Streamlink: DouyuTV plugin error of Unable to open URL

Created on 26 Feb 2019  ·  39Comments  ·  Source: streamlink/streamlink

The DouyuTV plugin function works fine yesterday. (2019/2/25)
At least
streams = streamlink.streams("https://www.douyu.com/3284257")
works through Python
But today it seems Douyu change some of its setting.
streamlink.exceptions.PluginError: Unable to open URL: https://capi.douyucdn.cn/api/v1/room/3284257?aid=wp&cdn=ws&client_sys=wp&time=1551152907&auth=0d8a7d105628da346bd088e19cdcdbca (401 Client Error: Unauthorized for url: https://capi.douyucdn.cn/api/v1/room/3284257?aid=wp&cdn=ws&client_sys=wp&time=1551152907&auth=0d8a7d105628da346bd088e19cdcdbca)

The `f3` is the encrypted js code, each 8 byte value represent a 4 char code. Those bit operations and there are four decryption steps in this algorithm.
The first decryption key is `0x405ca50f` in this example, you can decrypt the data by simple XOR operation like

for(var O=0; O < f3.length; O++){
v[O]^=0x405ca50f;
}

The second decryption key is two 32 bit hex values, `k2=[0x47fa3eef,0x209ff543]`.
For every element in the decrypted list there are bit operations using the `k2`, those operations are dynamic, different from each other. But elements are independent, you can decode the parts that you want without decoding the whole data. If we want to decode the data by this algorithm, we need to dynamic analysis those instructions by python.
The third decryption key is a list with 4 keys. `k=[0x3bbe6784,0x6cd672ae,0x96496df1,0xbfe901eb]` in the example. The algorithm decode the data with a fixed delta key and the providing key `k`.
The forth decryption algorithm is to xor values inversely for the data list. Then set the element at index 0 to 0x405ca50f.
After all, iterate the list, for each element the plaintext it contains from low bits to high bits, decoded by

for(var i=0; i strc+=String.fromCharCode(v[i]&0xff,v[i]>>>8&0xff,v[i]>>>16&0xff,v[i]>>>24&0xff);
}
```

The hard part is to get the dynamic bit operation code and get it run in python. Once get that done the remaining part is not so difficult.

Posting "same" doesn't contribute anything to this issue. Please don't do that.
If you want to contribute to this issue, please post a proper debug log, since this hasn't been done here yet, even though it is required for a full plugin issue report.

the new official app client of douyu, no Ads, no donation ....
you guys could have this as temporary one.

斗鱼可能的确要凉了，弄这种完全没打赏和广告的客户端出来，除了卖个人隐私跟踪，上市前冲量，有什么良性意义？
因此可估计，要凉的斗鱼还会疯狂封杀折腾取流工具。这次不过是刚开始。
另，貌似还有几个api没被封。

The live stream URL is formatted with rtmp_url/rtmp_live, it should be parsed out by POST to "https://www.douyu.com/lapi/live/getH5Play" with necessary parameters.
Unfortunately, DouYu TV seems split the steam data into lots of small pieces, each piece of stream data will be broken after a few seconds.

Hi, I am not sure if you have just provided another approach for API of DouyuTV, as I am not familiar with this plugin.

However, based on my observe, in the past, Streamlink would detect many HLS urls of DouyuTV for a given room url. A few of them store a single 4/8 seconds playable video stream data, the others are unpacked secondary video url, which constantly receiving stream data (4s/8s) and those split video streams' stored url are also trackable. So that is why I feel you may have just provided a different approach...

there are problems with the unfixed int length in python, I think a third-party library such as numpy is needed.

This code works as the js code, but when I test it with the latest ub98484234 on douyu.com, I found that the algorithm already doesn't work anymore.
latest ub98484234:

ub98484234('123456', 'a9d5e814227b2f321e037c0900041501', '1551475524')

"v=220120190301&did=a9d5e814227b2f321e037c0900041501&tt=1551475524&sign=166665b8585dc8b884b38910ba4b19c5"

js:

get_sign('123456', 'a9d5e814227b2f321e037c0900041501', '1551475524')
"6141e816d610e4dc58ce4f08f67c3984"

python:

pi@raspberrypi  ~  python3 douyu_sign.py 123456 a9d5e814227b2f321e037c0900041501 1551475524

  v0 += np.int32(p1 ^ p2 ^ p3)
6141e816d610e4dc58ce4f08f67c3984

Also noticed that the value of v will change over tt, it is actually some prefix with current date. 220120190301
here is the source, it is dynamic generated.

var vdwdae325w_64we = "220120190302";

If anyone familiar with decode compressed js code, it will be helpful to see what changed in the ub98484234 and find out if there is a way to implemented the working signature algorithm.

I tried change the date string according to the current timestamp, it still not work, 

def douyu_sign(rid, did, tt):
     print("roomid: {}, did: {}, tt: {}".format(rid, did, tt))
     date = datetime.utcfromtimestamp(time.time())
     time_str = '2201%d%02d%02d' % (date.year, date.month, date.day)
     cb = rid + did + tt + time_str

Other parameters such as k2 also changed when the algorithm changes. The only thing I am sure that the delta remain unchanged. To make it work we need to find ways to extract the k2 from the webpage dynamically and use that k2 to update the algorithm.

the cb's date may be related on the room last live date.

I tried another room that last stream was at 2018, the string in cb didn't work as '220120180919', the last time stream can be get from http://open.douyucdn.cn/api/RoomApi/room/+roomid
But what I've found that the returned v is exactly the current date and it has nothing to do with the tt that passed into the function.

So basically we only know v is the current date, we need to find out how algorithms change over time. IMO the current date string time_str plus some changing k2 has high probability.

So basically we only know v is the current date, we need to find out how algorithms change over time. IMO the current date string time_str plus some changing k2 has high probability.

By comparing the https://www.douyu.com/swf_api/homeH5Enc?rids={RoomID} js of different room ids, it seems that the encryption algorithm of each room is different(not only k2 and v), so the current API can only get js and run it to decrypt the sign.
Can anyone provide another API？

The `f3` is the encrypted js code, each 8 byte value represent a 4 char code. Those bit operations and there are four decryption steps in this algorithm.
The first decryption key is `0x405ca50f` in this example, you can decrypt the data by simple XOR operation like

for(var O=0; O < f3.length; O++){
v[O]^=0x405ca50f;
}

The second decryption key is two 32 bit hex values, `k2=[0x47fa3eef,0x209ff543]`.
For every element in the decrypted list there are bit operations using the `k2`, those operations are dynamic, different from each other. But elements are independent, you can decode the parts that you want without decoding the whole data. If we want to decode the data by this algorithm, we need to dynamic analysis those instructions by python.
The third decryption key is a list with 4 keys. `k=[0x3bbe6784,0x6cd672ae,0x96496df1,0xbfe901eb]` in the example. The algorithm decode the data with a fixed delta key and the providing key `k`.
The forth decryption algorithm is to xor values inversely for the data list. Then set the element at index 0 to 0x405ca50f.
After all, iterate the list, for each element the plaintext it contains from low bits to high bits, decoded by

for(var i=0; i strc+=String.fromCharCode(v[i]&0xff,v[i]>>>8&0xff,v[i]>>>16&0xff,v[i]>>>24&0xff);
}
```

The hard part is to get the dynamic bit operation code and get it run in python. Once get that done the remaining part is not so difficult.

I think use javascript interpreter is the best choice,
and ykdl already implemented it:

可以看这里，他们基本跑通了js注入方式，只要再装个nodejs 😂😂😂，返回流地址接口完全可用。
如投入实用还需要在

之上加一行：
exports = undefined;
另外，对应格式还需要改几个bug，看来斗鱼这次增加了不少可选流质量。

我提供另外1个思路：
首页的预览功能：https://playweb.douyucdn.cn/lapi/live/hlsH5Preview/{roomid}
同样需要加密，不过解密比较简单，和之前一样。而且auth貌似可以重复用，只需每次修改post的roomid就行了。
可以得到这样的内容：

{"error":0,"msg":"success","data":{"room_id":73440,"rtmp_cdn":"","rtmp_url":"https://hlsa.douyucdn.cn/live","rtmp_live":"73440rnreveCzTPB_550/playlist.m3u8?wsSecret=2645c3ead696b918af891de332a0f783\u0026wsTime=1551724300\u0026token=web-douyu-0-73440-86a8d06a5e2d3fbacfc6d18b59215a5a\u0026did=a1eae6d57d995b322fe5fd9000061501\u0026ver=2018061203\u0026st=0\u0026preview=1\u0026pt=3","client_ip":"115.192.209.72","cdnsWithName":null,"multirates":null,"is_pass_player":0}}

问题是得到的视频是550p的，更改后缀后无效。

不过m3u8格式的的封装比较简单，访问m3u8的链接：

@leis1015 这应该是流媒体服务器漏洞，可以深入研究，前几年有人也提过。
没搞起来，一方面要做播放器hack，更可能还是怕斗鱼封IP吧😇😇😇

提供一个思路，我用kali获取了手机上斗鱼直播的url地址，可以访问，也是flv格式。不过似乎加密了，打开流画面绿色，声音断断续续。但在我手机保持十分钟连接后，可用！

As noted before let's keep the discussion in English as this is an international project. Use free translation services if you have to, but if the discussion continues on like this I'm going to close and lock the issue.

用wireshark获得地址也没用啊，关键是写出可用的py插件

@Justsoos It would be nice to be able to resolve this without having to embed a full javascript interpreter.

@Erk but you do not, and need not to be so freaky as DouYu(huawei, mayun ... 997)'s programmers who under abnormal pressure of much more money paid, IPO, stock, option, KPI ...
Just live in DangXia, just use it now, and it will be changed soon by DY's nerds
;p

@Erk- could import Js2Py? To transform js code to py is too cumbersome.
